By the ubiquitin-proteasomes, cellular proteins are structurally degraded and turnover. Many essential functions and regulations of cells are regulated and controlled by these proteins. Recent studies indicated that many cancer types have been associated with aberrations in the ubiquitination pathway, which involves three enzymatic steps. Dietary phytochemicals have been identified as having the potential to inhibit carcinogenesis recently. As part of this group of phytochemicals, curcumin can play a crucial role in suppressing carcinogenesis by changing many reactions affected by the ubiquitin-proteasome pathway. Due to its ability to change some biological processes such as NF-κB, inhibit some cyclins, and induce apoptosis, it can be used as a drug in cancer treatment.
